Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

To use safelists and blocklists, the administrator must complete the following tasks:

Enable and configure the Cisco IronPort Spam Quarantine. Because the safelist and blocklist is 
accessed from the Cisco IronPort Spam Quarantine, you must enable this feature to use safelists and 
blocklists. For information, see 

.

Enable and configure the Safelist/Blocklist feature. Once the Cisco IronPort Spam Quarantine is 
enabled, you enable and configure the Safelist/Blocklist feature. You must also configure a blocklist 
action for blocklisted email (quarantine or delete). For information, see 

Backup and restore the Safelist/Blocklist database. When upgrading, you need to backup and 
restore the Safelist/Blocklist database. For information, see 

Synchronize Safelist/Blocklist databases. When end users enter safelist or blocklist entries, the 
settings are saved to a database which is periodically synchronized with a database that is used by 
AsyncOS when processing email. If the Cisco IronPort Spam Quarantine is maintained on an 
M-Series appliance, the administrator must configure the Safelist/Blocklist database to synchronize 
with the C-Series appliance. For information, see
